What are ETRACS ETNs?

ETRACS ETNs, are exchange-traded notes, an innovative class of investment products offering access to markets and strategies that otherwise may not be readly available to investors, and offer unique diversification opportunities in a number of different sectors and investment strategies such as income, commodities, MLPs and leverage.

UBS has filed a registration statement (including a prospectus, as supplemented by a prospectus

the SEC website at www.sec.gov. Alternatively, you can
